In reply to wilkie14c:
Last weeks episode was quite interesting...the two sasquatch hunters who said they could communicate with the creature by bashing those logs against the trees in the forest. They rapped out a series of loud knocks and lo and behold a few seconds later, there's an answering BOOM from far away in the forest.
Repeated the taps, and again - BOOM
Even I struggled to think of an explanation for that.
Then the biologist guy suggested that there may be an other group of sasquatch hunters somewhere else in the forest, and the two groups are totally unaware of each other, and the second group may think the first group is the sasquatch, and think they are answering 'his' call.
A complete coincidence that has evolved independantly of each other.
